The AN8049SH is a three-channel PWM DC-DC
converter control IC that features low-voltage operation.
This IC CAN form a power supply that provides two step-
up outputs and one Step-down or polarity inverted output
with a minimal number of external components. The
AN8049SH features the ability to operate from a supply
voltage as low as 1.8 V, and thus CAN be operated from
two dry-batteries. By Panasonic USA
